Kamoebas (カメーバ,   Kamēba) is a giant mutated turtle kaiju created by Toho that first appeared in the 1970 Toho film, Space Amoeba.

The result of the space amoeba Yog possessing a mata mata turtle, Kamoebas was used as part of the sinister alien's plan to take over the Earth. A group of humans on Sergio Island learned that the amoeba's weakness was the sonar given off by bats, and so unleashed a large swarm of bats from a cave, severing Yog's control over Kamoebas and Ganimes, a giant stone crab that the amoeba had also possessed. Kamoebas and Ganimes fought to the death, eventually falling into the crater of an active volcano, destroying all remaining traces of Yog. In Godzilla: Tokyo S.O.S., set over 30 years later, the carcass of another Kamoebas washed up on the shores of Japan with large gash wounds on its neck. The Anti-Megalosaurus Force determined that Kamoebas was killed by a larger predator: Godzilla. While Kamoebas did not debut in the Godzilla series and his only appearance in a Godzilla film came as a corpse, he has been featured in non-film media such as manga, comics, and even some video games. Kamoebas also made an appearance in the 1970's tokusatsu television show Go! Godman as one of Godman's enemies.


Kamoebas' name is derived from the Japanese word "kame" (カメ), which means "turtle," and "amoeba," a reference to Kamoebas' creator, the giant space amoeba Yog.

Kamoebas' scientific name given in Godzilla: Tokyo S.O.S., "Megalo matamata," is likely derived from the Greek word "Megalos," which means "giant" or "great," and "matamata," which comes from the mata mata turtle.


Kamoebas is a rock-brown color all over its body, with a spiky, rocky shell, and no real tail. Kamoebas' face has the same rocky texture as its shell, orange eyes with big, black pupils, two fangs on the upper jaw which bend outwards, small teeth, and a long, extendable neck. It has a smooth, lighter underside that still maintains a rocky look, and small legs each with powerful claws on four sharp toes.

In Godzilla: Tokyo S.O.S., Kamoebas is now dark blue in color opposed to rock-brown, but still keeps the spiky, rocky shell, and its tail is enlarged. It no longer possesses fangs, but keeps the small teeth and the extendable neck. The bottom of its claws are a light brown color, which could mean the rest of its underside is that color as well. The left side of Kamoebas' neck has a bloody scar, which was made by Godzilla.


Kamoebas was a mata mata turtle living on Sergio Island that was possessed and mutated into a monster by the alien amoeba Yog in his attempt to conquer the Earth. Although Kamoebas was killed along with Yog and Ganimes, at least one other Kamoebas existed on the island and was first sighted in 1987.

In Godzilla: Rulers of Earth, Kamoebas is an ancient creature that has existed since prehistoric times, and like most of the other kaiju in the comic is part of the natural balance of the Earth.


Showa Series

Space Amoeba

Kamoebas in Space Amoeba

After Ganimes was destroyed, Yog turned to a mata mata turtle transformed it into Kamoebas, while also creating another Ganimes. However, bats fled from a nearby cave and caused Yog to lose control of the monsters. Kamoebas and Ganimes battled each other up the mountain in the center of the island and both fell into the volcano, destroying themselves and Yog forever.

Go! Godman

Godman vs. Folgon and Kamoebas

Kamoebas in Go! Godman

Kamoebas suddenly appeared at a beach and terrorized some beach-goers. The couple called out for Godman, who heard their plea and appeared on the scene in a matter of seconds. Kamoebas was confronted by the hero, and attempted to defend itself any way it could; mostly scratching and biting while rising on its hind legs. Despite making a valiant effort, Kamoebas was eventually outmatched. However, upon attempting to kill the monster with his God-Sparks, Godman realized that Kamoebas' carapace was too strong to kill it in this way. Another monster, Folgon, then suddenly appeared, and Godman left to fight it, ultimately allowing Kamoebas to escape with its life.

Millennium Series

Godzilla: Tokyo S.O.S.

A dead Kamoebas, the first specimen of its kind seen since 1987, washed ashore in Japan in 2004, with gaping slash wounds in its neck. The J.X.S.D.F. surrounded the carcass and examined it, determining that it was probably attacked by a huge predator, most likely Godzilla, and eventually died from its wounds.


  • Kamoebas has a hard carapace.
  • Kamoebas has an extendable neck.

GODZILLA: Monster Apocalypse

The first Kamoebas appeared in the Philippines in 2002, just two days after Dogora's defeat. The second Kamoebas, designated "Kamoebas II," appeared in Guam. The fourth Kamoebas, Kamoebas IV, washed ashore dead on Odo Island in 2030, and was the first evidence for the existence of Godzilla.[4]


Godzilla: Rulers of Earth

Kamoebas was first seen in a flashback where it came to shore while Gorosaurus and Megaguirus fought. It was classified as a "water kaiju" by the Shobijin. Kamoebas was captured by the Trilopods at some point and was imprisoned in their hive. King Caesar recognized Kamoebas as a monster from his time and freed him before freeing all of the other imprisoned kaiju. Kamoebas then assisted in the final battle against the Trilopods and Magita, and followed Godzilla out to sea along with the other monsters once the battle was over.

  • Originally, Kamoebas' role in Godzilla: Tokyo S.O.S. as a corpse that washes ashore after being killed by Godzilla was filled by a Liopleurodon. Toho decided to replace the Liopleurodon with an existing kaiju rather than create an original creature just to have it appear as a corpse. Director Masaaki Tezuka proposed using Anguirus in the role, but Toho denied the request, wanting to keep Anguirus alive for possible use in a sequel. Tezuka proposed Gamera next, and Toho countered with the only turtle kaiju they held the rights to: Kamoebas.[5]
  • Godzilla: Tokyo S.O.S. establishes that a Kamoebas was sighted in 1987, even though the Kamoebas seen in Space Amoeba died along with Ganimes and Yog in 1970. It is possible that, like he had done with Ganimes, Yog possessed more than one mata mata turtle on the island and created multiple Kamoebas specimens.
  • The Giant Turtle from the Godzilla: The Series episode End of the Line shares some traits with Kamoebas, most prominently its spiky shell and extendable neck.
